Clamp type wheel hub for BD10. It is made of brass with a high specific gravity, and it weighs about 3.6 g in one set compared to standard aluminum (standard 1.85 g / brass 5.45 g). It has the effect of increasing tire traction by increasing the unsprung weight, but especially at outdoor circuits etc. it is attached to the front and back to improve grip. In addition, when you want to adjust the front and rear traction balance, it is effective as one of the settings, such as using it only for the front to improve turning performance and using it only for the rear to increase stability.
The thickness of the hub is 4.0 mm, which is the same as the standard, and there are two hubs.
